Its prism has 2n vertices, 3n edges, and 2 + n faces. Take a polyhedron with V vertices, E edges, and F faces. Its prism has 2V vertices, 2E + V edges, 2F + E faces, and 2 + F cells. Take a polychoron with V vertices, E edges, F faces, and C cells. Its prism has 2V vertices, 2E + V edges, 2F + E faces, 2C + F cells, and 2 + C hypercells ...
